Heat a large skillet over medium-high heat. Brown the pork sausage, crumble, and drain the excess fat from the pan. Saute the onion and garlic with the pork until tender, about 5 minutes. Stir the pork mixture into the bean mixture.

Brown the turkey sausage and add into the bean mixture.

Bake, covered, for 3 to 5 hours in the preheated oven, removing the lid for the final 45 minutes.
